Dear Anurag ,

No ,it is not the only option for you. If you are interested in Management then you can choose any of specialization like Marketing ,HR, Operation and  many more but you are from agriculture background so it will good for you because you had know so many things in your bachelor degree but if you wants to go through another sector then you can defiantly try .But it will depends upon your interest, and your skills .

Hope it will helpful

Thanks
